RDKit – SMILES Manager

Hello everyone, In this post I will present you the new version of the RDKit-SMILES Manager module that I integrated in the SAMSON platform. As some of you know, RDKit is an open source toolkit for cheminformatics which is widely used in the bioinformatics research. One of its features is the conversion of molecules SMILES strings to a 2D and 3D structures. The module interface presents two tabulations: Manage SMILES and Replace fragments. I will present these two sections one by one…

Normal Modes Advanced

Hello all, Welcome to this tutorial, I will present you the functionalities of the Normal Modes Advanced (NMA) SAMSON Element. This SAMSON Element computes the nonlinear normal modes of a biomolecular system (protein, RNA, DNA) very quickly using the NOLB algorithm developed by Alexandre Hoffmann and Sergei Grudinin (J. Chem. Theory Comput., 2017, 13 (5), pp 2123-2134, DOI: 10.1021 / acs.jctc.7b00197.). First, you have to import a structure. For this tutorial I used the 1vpk PDB entry. Then, you launch the NMAL module…

Computing non-linear normal modes of biomolecules

Hello all, Welcome to this tutorial. Here, I will present you the functionalities of the Normal Modes Analysis Lite (NMAL) SAMSON Element. This SAMSON Element computes the nonlinear normal modes of a biomolecular system (protein, RNA, DNA) very quickly using the NOLB algorithm developed by Alexandre Hoffmann and Sergei Grudinin (J. Chem. Theory Comput., 2017, 13 (5), pp 2123-2134, DOI: 10.1021 / acs.jctc.7b00197.). First, you have to import a structure. For this tutorial I used the 1vpk PDB entry. Then, you launch the…
